摘要
原油中含有大量盐、含硫化合物及酸性物质,对常减压整流装置及泵等设备产生了腐蚀破坏,严重影响着原油炼制工业的正常生产。本文对常减压蒸馏装置的腐蚀情况进行了综述,分析了产生腐蚀的主要原因,及针对各种现象所做的一系列工艺防护,设备防护以及安装先进的检测设备,从而提高炼油厂的运行周期和经济效益。
Crude oil contains large amounts of salt,sulfur compounds and acid substances,and they cause atmospheric and vacuum distillation unit and other equipments corrosive damage,which has seriously affected normal production of crude oil refining industry.In this paper,situation and reasons of corrosion in atmospheric and vacuum distillation unit were reviewed.For a variety of phenomena,a series of process protection and equipment protection were carried out,and advanced testing equipment was installed to improve the operation cycle and economic benefits of the refinery.
